MIKE SAPUZAK, OF NEW YORK, N. Y.

SUBMARINE FENDER.

Application filed June 20, 1918.

To all whom it may concern Be it known that I, MIKE SAPUZAK, a subject of the Emperor of Austria, residing at New York, county of New York, and State of New York, have invented certain new and useful Improvements in Submarine Fenders, of which the following is a specification.

This invention relates to improvements in ship fenders, and particularly to types adapted to divert torpedoes and l1ke submarine missiles.

The principal object of the invention is to provide a protecting device engageable with the hull or sides of the ship by means of which projectiles of the under-sea type are warded or fended ofi? from the hull of the vessel.

A further object is to provide a fender supplied with resilient mountings so as to yield under the impact of a blow from a projectile, the fending elements being of a flexible nature and the supports by which they are connected.

These and other like objects are attained by the novel construction and combination of part hereinafter described and shown in the accompanying drawings, forming a material part of this disclosure, and in which Figure 1 is a top plan view, showing a con ventional type of ship and indicating the application of the invention.

Fig. 2 is an enlarged fragmentary transverse sectional view, taken through the hull of the ship and the fending elements applied thereto, and

Fig. 3 is a similar view of the same, but showing a modified form of net support.

Arranged eircumjacent to the hull 10 of the vessel 11 are a plurality of brackets 14:, from which extend rigidly and directly outward, tubular arms 15, receptive of bars 16, the same moving telescopically within the tubes 15, which are formed with slots 17, receptive of pins 18 set in the bars 16, limiting their movement, and surrounding the bars 16 and tubes 15, are coiled compression springs 19, the same pressing outwardly against the fender plates 20, through which pass the extending ends of the bars 16. The plates are engaged with the bars by flanged sleeves 21 and 22 arranged respectively upon their inner and outer sides.

Rigidly engaged at the outer ends of the bar 16 are flanges 2 1 to which are secured woven wire nets 25 so as to be supported Specification of Letters Patent.

thereby, and it will be obvious that upon pressure being applied to the net 25, the same will be pressed inwardly toward the hull of the vessel, against the springs 19, which will return the nets to their original position when the pressure is removed.

Extending out from the gunwale of the ship are a plurality of bars 28 carrying pulleys 29 at their ends, over which run cables 80, attached at their lower ends to the bottoms oif the nets 25, and passing over the edge of the ship to hoisting devices 31, which may be manually or mechanically operated.

In the modification shown in Fig. 3, the flanges 21 and 22 are omitted and in place thereof, there are rigidly engaged to the outer extending ends of the bars 16, collars 28, while attached to the outer sides of the plate 20 are bent fiat springs 30, their outer ends engaging with extensions 31, of the rod 16, which are hinged at the ends of the rods or bars 16 by the pins 32, so that when pressure is exerted upon the nets 25 midway between the supports 31, the nets may fold inwardly, the supports pivoting upon the pins 32 in an obvious manner, thereby creating a resilient efl ect in addition to that secured by the coiled springs 19.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is.

1. In a ship tender, the combination with a plurality of brackets mounted in vertically spaced relation upon the hull of the ship, tubular arms extending horizontally from said bracket, bars slidable in said tubular arms, means for limiting the motion of said bars in said arms, fender plates in which said bars are slidably engaged, coiled compression springs extending between said brackets and'said plates whereby the plates are pressed outwardly, and a net engaged at the outer ends of said bars adapted to receive the impact of a blow.

2. In a ship tender, the combination with a plurality of brackets engaged at spaced intervals around the hull of a ship, said brackets being arranged in pairs one above the other, tubular arms rigidly engaged with said brackets extending directly outward therefrom, bars slidable in said tubular arms, means for limiting the motion of said bars with respect to said arms, rigid plates carried by said bars, collars secured to said bars to limit the outward movement of said plates, joints formed in said bars exteriorly of said plates, springs carried by said plates whereby said joints are normally extended directly outwardly, and coiled compression springs between said plates and the first named brackets.

'3. In a ship fender, the combination with the hull of a vessel, of tubular arms extending directly outward therefrom, said arms being arranged in pairs, one above the other, and 'at spaced intervals upon the hull of the vessel, bars slidably received in said arms, nets carried at the extreme outer ends of said bars, plates slidably arranged on said bars, springs encircling said bars and tubular arms adapted to press said plates outwardly, collars fixed on said bars, adapted to restrain the extreme outer movement of said plates, joints formed in said bars exteriorly of said plates, and means secured to said plates whereby said bars are held normally outward, but permitted to bend inward toward each other when pressure is exerted upon said nets.

In testimony whereof I have afiixed my signature.
